High market demand for wireless networking services and devices has resulted in increased complexity of an infrastructure of networking testbeds because of the scale, diversity and exploitation levels of the involved resources. In this paper, we address the problem of managing the infrastructure of large wireless networking testbed by adopting a semantics-based approach to knowledge-driven system...
In this paper, we address the challenges in facilitating the intra-band coexistence of WiFi and LTE technologies in multi-RAT networks and propose a semantic coordination protocol that improves the communication performance among inter-network devices. Effective communication in LTE networks is a critical task to achieve as the heterogeneity of the devices and coexisting technologies arises. This...
If several different systems operate in the same frequency band, in order to effectively use the available spectrum there has to be some coordination between them. The coordination is especially important if the systems are not designed to operate in such an environment. The initial and a very important part of the coordination process is the acquiring of the spectrum usage map or spectrum sensing...
The CoordSS experimentation framework aims to provide a solid practical evidence that testbeds and other experimentation infrastructure provided by EU FP7 FLEX project is capable of supporting advanced experimentation with proposed use of LTE Advanced in unlicensed 5 GHz spectrum (LTE-U). By integrating technologies such as spectrum sensing, various coexistence mechanisms between legacy unlicensed...
In this paper we present challenges for full integration of services in today's networking testbeds, and show how they can be addressed by applications based on the Semantic Web. We demonstrate particular implementation of such a web application, and discuss benefits of using this application in creation of tests that can be run in networking testbeds environment.
